Diagnostic characters.

Female. Thorax dark brown to blackish. Abdomen entirely blackish brown or first three segments slightly paler laterally. cx1 entirely yellow or darkened in basal half, cx2 and cx3 entirely dark brown to black. Fore trochanter yellow basally, brown apically. Mid and hind trochanters brown. f1 and f2 yellow, f3 yellow with brown apical fifth. Tibiae yellow, apically slightly darkened, with dense brown setae. Scape, pedicel and flagellomeres brown. Mouthparts pale yellow. Apical palpal segment 1.8-2.2 (n=5) times as long as penultimate segment. Wing tip shaded on about apical third, with darkened area along fore margin. All veins reach wing margin, M2 sometimes basally obsolete or very weak, A1 ending close to, sometimes fused into base of CuA2. Terminalia brown. Cercus distinctly two-segmented, apical segment small, ovate. Gonapophysis IX membranous, widely protruding apically, not visible in lateral view. Tergite VIII larger than tergite IX. Sternite VIII apically with shallow medial incision, moderately emarginated basally.

Male. Coloration and other non-terminal characters including palpi similar to female. Apical palpal segment is 1.7-2.1 (n=5) times as long as penultimate segment.

Remarks.

This species was originally described by Laštovka and Matile (1974) based on Mongolian material and subsequently widely recorded in Europe. Chandler (2005) did not include Greenomyia mongolica in the European list and assigned all records to Greenomyia theresae , a species described from northern Italy by Matile (2002). Careful comparisons of type material of both species at MNHN in Paris (independently undertaken by two of the authors, OK and JK; the holotype of Greenomyia mongolica deposited in the Hungarian Natural History Museum was not available for the study) did not indicate any substantial differences in their male terminalia. The minor diagnostic characters as indicated in the original description and illustrations by Matile (2002) are liable to different angles of views only. Consequently we have come to the conclusion that Greenomyia theresae at present state of knowledge must be treated as a junior synonym of Greenomyia mongolica and that all published records in Europe should rather be associated with the latter. In addition to the studied type material, we also compared the terminalia of female specimens from the Russian Far East, Estonia and northern Greece without finding any reliable differences. Moreover, Papp (2000) confirmed conspecificity when he compared central European material from Hungary with the Mongolian type material. Male terminalia are figured by Laštovka and Matile (1974) and subsequently by Matile (2002), while female terminalia have previously been figured by Zaitzev (1982) and Kurina (1997). Our association of males and females are based on multiple simultaneous findings in trap samples (see above) that agrees with previous descriptions of the female. In the Pre-Balkan mountain range in Bulgaria, the species has been collected in xerotermic oak forest ( Bechev 2000). The species was quite common in samples taken in a bait trap, operated on the basis of a mixture of fermenting sugar and red wine, in southern Estonia (see also Kurina 2006). The above-mentioned specimens from Greece are the first records from the country.
